To all whom z'z may concern:

Be it known that I, RAYMOND B. GIL- CHRIsT, a citizen of the United States, and a resident of Newark, inthe county of Es- 5 sex and State of New Jersey, havev invented certain new and useful Improvements in Drink Mixers, of which the following is a full, clear, and exact description.

The invention relates to drink mixers. In machines for this purpose, the liquid constituents of the drink to be mixed are usually poured into a receptacle which is generally designated a shaken from many different containers disposed away from the '15 mixer. The receptacle, with these constituents therein, is brought to the mixer and placed in operative relation thereto and is removed from the machine after each mixing operation to discharge its contents. This is rendered necessary, because so many different ingredients and flavors are used in making drinks that they are, in nearly all cases, mixed individually. It is usuall necessary to run the agitator for a consi erable period to properly blend or mix the constituents and, therefore, it is desirable that provision be made for retaining the.

1 receptacle and agitator in operative relation to permit the dispenser to perform other duties during the mixing operation. In drink mixing, it thus becomes necessary to frequently place the receptacle conta-ining the constituents into cooperative relation to the agitator and to withdrawit from the machine todischarge its contents and cleanse the 'receptacle between, mixing operations. l

A desideratum in this art is to expedite and simplify the. operations necessary to t0 bring the receptacle and agitator into cooperative relation, to maintain them in such relation, in starting and stopping-'the motor, and in the removal of the receptacle to avoid the necessityof manually manipulating the receptacle into operative position and withdrawing it .therefrom and toadditionally perform some separate step-or op.'-

eration, such as lowering the motor and vagitator together, or shifting the agitator-r and its shaft into the receptacle and relatively to the motor, or raising' and locking a receptacle support to establish and maintain cooperative relation of the receptacle and agitator or to control the operation of the machine. Another desideratumein this art is to simplify the machine by dispensing with movable connections in and for the mechanism for driving the agitator.

@ne object of the present invention is to provide an improved drink mixer in which these additional operations or steps are dispensed with and in which manual shift of the receptacle is utilized to completely control the operation of the machine and the securing of the receptacle and the agitator1 in cooperative relation. By dispensing with the necessity of these additional steps or operations, the timeof the dispenser in performing them is saved and the service is im roved.

nother object of the invention is to rovide a receptacle controlled machine w ich is equipped so that the receptacle can be manipulated to controlits locking into 0perative position around the agitator, its release for withdrawal, and the starting and sto ping of the motor.

nother object of the invention is to provide a machine of this type inwhich movable connections in and for the driving metianism for the agitator are dispensed wit Another object of the invention is to provide a machine which is simplein construction, which may be easily and readilyoperated and which is eiicient rin operatlon.

Other objects of the invention will more fully appear from the following descrip-` tion.

The invention consists in the several novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings: Fig. 1 is a section of aV machine embodying the invention, parts being shown in elevation, the recepitacle being shown in operative position; ig. 2 is' a simil-ar view showing lthe receptacle removed from its holdin means. Fig. 3 is a. perspective of the sli able holder for the receptacle anditsguideway. Fig. 4 is a section taken Online 4 4 of Fig. l.. Fig. 5 is a perspectiveJ of the supporting ledge and inclined guide for the receptacle? The invention is exemplified in a machine comprising an electric motor 8 which is supported at the upper end of a2 standard 9 which isl channelled in cross-section and.

' serves as a stationary support for the motor.

Its lower end is rigid with a base 10 which is usually adapted to rest on a counter or table. A shaft 11 secured to the rotor of the motor projects downwardly from fthe motor case and is provided at its lower end with a suitable agitator 12 for mixing the constituents of a drink, as well understood in the art. Shaft 11 is of sufficient length so that the agitator may be disposed in the constituents of a drink to be mixed' near the bottom of an open-topped receptacle 19 held below the motor and containing said constituents. There is sufficient clearance below the agitator to permit the receptacle 19 to be placed beneath and around the agitator without spilling its contents and without the necessity of lowering the agitator into the receptacle. In the present invention the relationship between the agitator and the motor or between the agitator and the -base are not varied and the receptacle only is manipulated in establishing cooperative relationship between the receptacle and the agitator so that movement of the agitator or the agitator and motor are not necessary for this purpose. The case of the motor 8 is rigidly secured by screws 13 to lugs 14 which are integral with the upper end of the standard. A case 15, containing an electricalswitch-of usual construction and having its members connected to control the motor 8, is fixedly secured to the outside of the motor-casing of the motor. A springpressed button 16 operates the switch in the case 15 to close the circuit and causethe motor 8 to run while the button is pushed upwardly and to open said circuit to stop the motor when the button is released. The switch-members in the case 15 may be of standard construction, as well understood in thefart, so that detailed illustration has not been deemed necessary. A pair of yielding contact-strips 16a, adapted to enter a switchsocket of usual construction, project rearwardly from thel case 15, so -thatithe necessary electrical connections to supply current to the motor will be made by pushing an ordinary conductor socket which is adapted to receive said contact-strips and is connected by a iiexible cord conductor to a suitable source of energy, into connected relation with said strips.-

The lower portion of the standard 9 is provided with a backwardly and upwardly sloping or inclined front face 14 which is arcuate in cross section, conformably to the periphery of the receptacle to form a guideway or surface over which the receptacle will freely slide in its movement to and from its operative position around the agitator. A slot 15 is formed in the standard 9 above the guideway 14` to form a guideway or track for a slidable holder 16'. The sides of holder 16' are formed with grooves 18 to receive the margins of the slot 15 and slidably retain the holder in the standard. This holder is slidable to guide the upper end of the receptacle while it is raised into and lowered from its operative position, so that the receptacle cannot strike the agitator while it is being placed into and removed from its operative position. This holder is also adapted to lock the upper portion of the receptacle while it is supported in operative position. For these purposes, the holder 16' is formed with an arcuate groove 18' conforming transversely to the wall of the receptacle, adapted to receive one side of the upper margin or rim of the receptacle and hold it locked 'against lateral movement in any direction. In front of the groove 18', the holder is provided with a hook or member 17 which is adapted to extend into the upper portion of the receptacle at one side thereof and to engage its inner periphery. The upper portion 2() of the rear face and the lower portion 20a of the front face of groove 18' are inclined upwardly and rearwardly to permit limited tilting of the receptacle when its lower end is free in effecting the removal of the receptacle from the groove and to permit its insertion therein'. The lower portion 21 of the back face below inclined portion 20 and the upper vertical portion 20' of the front face of groove 18' are disposed to cooperate and lock the receptacle when it is supported from'below in its vertical and operative position. The lower portions of the faces of the groove 20 are flared to direct the upper rim of the receptacle into the groove. By forming the faces of the groove so that only a limited movement. of the receptacle is possible. the

latter will be secured, so that it cannot be tilted into position to cause it to strike the agitator during its insertion and removal. Holder 16' will be automatically raised by the receptacle and lowered therewith. At

the upper end of guide 14, aledge 22 with' an arcuate back 22a conforming to the peripheryof the receptacle, is provided to form a rest or seat for the lower rim of the receptacle, and a rearwardly and downwardly inclined Shoulder 22h, adapted to engage the inner edge of the lower rim of the receptacle, is adapted to hold the lower rim of the receptacle on said seat and so that, when the upper portion of the receptacle is locked in the holder 16', the entire receptaclewill be securely locked in operative position.

A lever 23, for" operating the switchbutton 16 to control the operation of the motor 8, is pivoted to the standard by a pin 24 has its upper end formed with a cam 25 to shift button 16 upwardly, extends through a guide-way 26 in the vertically slidable holder 16', and is provided with a cam portion 27 which is acted upon by the Messes `iront and rear edges of said guideway to sli-liet the lever forwardly andbackwarrlly as 'the holder 16' is lowered and raised to cause the lever to operate the switch-button 15D into position, to close and open the switch torcontrolling the motor 8. A stop 22% is provided on lever 23 to limit the downward movement of the holder. 4The recepole illustrated is provided with en upper r-hand 30 and a lower wear-band 3l.

chine to be idle, the holder ltr in its lowered position, es illus- 2. The operator place the arcuate guideslide it upwardly thereon. This e 4pper of the receptacle grec e i8 in holder 16? et t will Joe substantially parallel to 'the Teac-es and 2G oiE groove. upper rim has entered the arcuate inclined faces will limit the ng and also the lateral movement of acepto-cle, so that it cannotstrile 'the agimtor while it is being; raised into `and lowred its operative position.. The opor, continuing the manual liit ol the receptacle, will raise the holder, the lower portion of the receptacle sliulingga on the guide-ieee le while its upper portion is se- -ured in the holder 16. 'When the holder trikes the upper end of slot l5, it will be arrested and, at such time, the bottom oi the receptacle will have cleared the lu@ 22 on ledge 22. The operator, exerting a aclaward pressure upon the receptacle will :force its lower end against the back face 223- of seat 22 and. then release the receptacle. Thereupon, the lower rim will pass into locked relation with the lug 22b to lock the lower portion of the receptacle on the seat 22 and holder 16 will follow the receptacle and lock its upper portion against movement in any direction. -v Holder 16', during' its lift by the receptacle, will, through caml 27 and guide-way 26, vshift the lever 23 backwardly to lift button 16 and close the switch for the motor 8, so that the agitatorl will ,commence to rotate before thecrece tacle is llocked in its operative position. ver 23 will continue tohold the switch-buttonin position to cause the motor torun as long as the receptacle remains in theymachine. When the mixing operation has been completed, the operator will grasp receptacle 19. raise it slightly, then )tilt 1t forwardlysuciently to clear lug 22a and lift it oft` ledge 22. Thetilting movement of the receptacle is positively limited by the inclined surfaces at the `back and front of groove 18 in the holder, so that the vessel cannot be tilted excessively and strike the rotating agitator. Then, the operator will manually lower the receptacle and during such lower- CU (D ing` movement, the holder 1 6 will be interloclzed with it, so that itwill beI positively lowered thereby until it is arrested by stop 28. During this lowering movement, the holder it will act upon cam 2"? to shift lever 23 to release button le and cause the motor to stop at the desired predetermined time. By continuing the lowering oil the receptacle after the holder i6 has been arrested, the upper rim of the receptacle will he withdrawn from the holder and released :for withdrawal from the machine. 4 The invention enempliiies a machine oi the character described, in which the upper rim oi vessel is positively guided while it is manually shiited into and out of operative position; in which the receptacle will loe secured and guided so that will not strilre the agitator while it is being placed into and removed rfrom operative position; in which the recorte-le is adapt-ed by its own manipulation to he locked and released from its operative position; in which the receptacle positively operates switch-lever to control the operation oi the in which the supporting standard or column and the receptacle guide and a stationary member el the automatic receptacle-guidingmeans are termed integrally, which materially simpliiies the construction, and avoids the necessity and cost-oi5 a column which is separate from the stationary-support and guide; and which is simple in construction.
